PC doesnt turn on pls help
one day i put my custom built pc (£500) on sleep for several hours and when i came back the pc would seem to turn on normally but the monitor, mouse and keyboard. After a while the pc would turn off as if it gave up. 2 months later i now have replaced the psu and case and its doing the exact same thing. Does anyone know whats going on here? some help would be much appreciated

Hibernate writes the RAM contents to disk and shuts down fully. Waking up is like a cold boot. If hibernate works fine, then the issue is specific to sleep mode.
